II. Read the following passage carefully, then do as directed : (5 marks)
Thinking about how we will be travelling in 10 or 20 years is very interesting. Will we still be using planes or will we be flying our cars from Paris to London? Here are some suggestions.
- SkyTrain: Currently being developed at NASA, SkyTrain looks like the monorail at Disney World. Moving at 240km/h and using small amount of energy, it could be the future of city transportation. SkyTrain has the passenger capacity of a 6-lane highway.
- Flying cars: Zhu Wenxi and Lai Zexin, Chinese students, have designed a solar-powered flying car that doesn’t need a runway to take off. If you have about 200 hundred thousand dollars, you will own this vehicle soon.
- An electric mininus: The minibus Cameo, designed by Martin Pes, can carry 32 passengers but it is small enough to get its way out of a traffic jam. Its electric motor and low weight mean that it can be recharged in seconds while stopping and it has zero emission.
- An eco-taxi: Taxis are bad for the environment and traffic jams. We enter eco-taxi, and individual taxis form a train powered by solar panels.
1. Decide whether the statements below are True (T) or False (F) : (2,5 marks)
a. SkyTrain is fast but cannot be used as a means of transport in the city. …………
b. Flying cars designed by Zhu Wenxi and Lai Zexin run on solar energy. …………
c. A long runway is necessary for flying cars to take off. …………
d. Because it is small, an electric minibus can avoid traffic jams. …………
e. Several eco-taxis can form a line moving together, using solar energy. …………
2. Answer the following sentences: (2,5 marks)
a. How fast can SkyTrain travel?
………………………………….............................................................................................
b. Where are the designers of flying cars from?
……………………………………………………………………………………………………………….
c. How much money does a flying car cost?

* Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 24 to 30.

Almost all living things ultimately get their energy from the sun. In a process called photosynthesis, plants, algae, and some other organisms capture the sun's energy and use it to make simple sugars such as glucose. Most other organisms use these organic molecules as a source of energy. Organic materials contain a tremendous amount of energy. As food, they fuel our bodies and those of most other creatures. In such forms as oil, gas, and coal, they heat our homes, run our factories and power our cars.

Photosynthesis begins when solar energy is absorbed by chemicals called photosynthetic pigments that are contained within an organism. The most common photosynthetic pigment is chlorophyll. The bright green color characteristic of plants is caused by it. Most algae have additional pigments that may mask the green chlorophyll. Because of these pigments, algae may be not only green but brown, red, blue or even black.

In a series of enzyme-controlled reactions, the solar energy captured by chlorophyll and other pigments is used to make simple sugars, with carbon dioxide and water as the raw materials. Carbon dioxide is one of very few carbon- containing molecules not considered to be organic compounds. Photosynthesis then converts carbon from an inorganic to an organic form. This is called carbon fixation. In this process, the solar energy that was absorbed by chlorophyll is stored as chemical energy in the form of simple sugars like glucose. The glucose is then used to make other organic compounds. In addition, photosynthesis produces oxygen gas. All the oxygen gas on earth, both in the atmosphere we breathe and in the ocean, was produced by photosynthetic organisms. Photosynthesis constantly replenishes the earth's oxygen supply.

Organisms that are capable of photosynthesis can obtain all the energy they need from sunlight and do not need to eat. They are called autotrophs. Plants are the most familiar autotrophs on land. In the ocean, algae and bacteria are the most important autotrophs. Many organisms cannot produce their own food and must obtain energy by eating organic matter. These are called heterotrophs.

Many of the world’s cities lie under a permanent blanket of smog. People are concerned about global warming, and fuel prices just keep going up and up. It’s no surprise therefore, that in recent years, car manufacturers have been put under pressure to invent a vehicle that is both cheaper to run and better for the environment. Finally, after much trial and error, it seems as though they might be making progress, and the future of the car industry is beginning to look a little “greener”.

One of the first ideas which car manufacturers tried was to replace engines which run on fossil fuels with electric motors. Unfortunately, these vehicles had several drawbacks and they didn’t sell very well. The problems were that the batteries of these electric cars ran out very quickly and took a long time to recharge. Also, the replacement energy parts were very expensive.

However, the idea of electric cars has not been scrapped altogether. Car manufacturers have improved the concept so that environmentally friendly cars can now be efficient and economical as well. This is where the hybrid car, which has both an electric motor and a traditional petrol engine, comes in. The electric motor never needs to be recharged and it is much better for the planet than a traditional car.

In a hybrid car, the engine is controlled by a computer which determines whether the car runs on petrol, electricity, or both. When the car needs maximum power, for example, if it is accelerating or climbing a steep hill, it uses all of its resources, whereas at steady speeds it runs only on petrol. When slowing down or braking, the electric motor recharges its batteries.

Hybrid cars are better for the environment because the electric motor can help out whenever it is needed and they have a much smaller engine than a traditional car. Also, hybrid cars on the market are made using materials such as aluminium and carbon fibre, which makes them extremely light. Both of these factors mean that they use far less petrol than normal cars, so they produce less pollution.

Of course, hybrid cars aren’t perfect; they still run on fossil fuel and so pollute the environment to some extent. However, they may be the first step along the road to cleaner, “greener” cars. Car manufacturers are already working on vehicles which run on hydrogen. The only emission from these cars is harmless water vapor. These are still some way in the future, though, as designers need to think of cheap and safe ways of producing, transporting and storing hydrogen, but at last, it looks like we might be heading in the right direction.

Hybrid cars are better for the planet because_______.

A. they produce less harmful gases

B. they are made of special materials

C. they use different fuel to normal cars

D. the electric motor is smaller than a normal engine
